I have been using a few Wikis over the time, I even looked into the code of the engine of some to add some features and if somebody asked me which one I would choose to install, I could cite phpwiki, mediawiki, jspwiki, dokuwiki, trac, zwiki or even confluence (if you’re into this kind of software).
In a sense, Wikis are nice online easy-to-manipulate collaborative webpage creation tools.
One problem I have with wikis is that everything is based on linking. You usually have a main page, you write text and create links to new pages. From there, you create the pages, and so on. But if I have a wiki, sometimes I don’t feel like every page is related, even to a (de facto, human created) index. I could create an orphan page and find it back again later through the search engine, but this also seems unnatural.
The way I see it, it is related to mind-mapping except that most so-called mind-mapping softwares are graphical-display-oriented and local applications.
Other related approaches are the use of tags by some web applications (eg. GMail), or the everything-is-a-database (eg. winfs which was once a feature of Microsoft Longhorn). Another application of the tags can be seen with TextSnippets, where we can see a clear disadvantage in one presentation: the number of tags is growing and represents some kind of anarchy again.
